WEATHER STRIP.

-Application filed August 31,1927. SeriaIlN'o. 21.6;631.

"This invention relates to a weather strip, and particularly to ametallic construction having a yielding contact with awindow or door.

In ordinary metallic weather strip construction there is considerablefrictional resistance betweeninterlocking parts which renders the windowdiflicult to operate, par-' To avoid such objections I provide afreelymovable side strip spring tensioned into contact with the sash andenclosed by a casing having a wall opposite the contact face secured tothe window frame to form an abutment for the tensioning' spring.

This side unit may be mounted upon an end:

strip secured to the-frame and having a yielding contact plate engagingthe end of the sash and a stop member against which the casing bears.The parts so far described may be further enclosed by an angle closureplate connected to the casing.

This construction forms an air-tight joint at the sides and ends of thesash which economizes fuel by preventitng the entrance of air or dirtand prevents rattling of the sash through the tensioning of the strips.

This tensioning is so determined as to com- 1 pensate for Warping,swelling or shrinkage of the sash or cooperating beads so that the sashunder all conditions is easily slidable as any sticking or bindingthereof is eliminated.

The strip structure also forms a parting bead between the sashes or maybe used as a stop to be engaged by a door when closed.

The invention has for an object to provide a novel and improvedconstruction of weather strip including a side strip having a lateralclosure member and a fixed casing with a cooperating wall between whichand the strip a tensioning strip is disposed.

A further object of the invention is to present an improved structure inwhich the side strip is movably mounted upon a fixed end strip having ayielding contact face against the end of a sash.

Another object of the invention is to provide animproved construction inwhich the strips ures of the drawing.

strip ;unit' forms a bead or strip having a finished appearance andadapted to bear against the side of the closure with which; itcooperates.

Y Other and further objects and advantages of the invention willbehereinafter set forth and the novel. features thereof defined by theappended claims.

Like reference. numerals; designate corresponding parts throughout theseveral fig The inventionis adaptedfor. various applications inrelationtothe sashes of a WHI- dow and the stop members of a door orsimilariclosure. As applied to a, window-,-shown in Figures land 3, thenumeral 10 designates the window frame. whichvmay be -of any'desired-construction and -,is provided with a vertically extendingchannel -11-and also with an inner; strip or head 12 against whichthesash member 13 abuts. At the outer face 14 ,ofrthe sashmyimprovedside strip is applied and this, comprises a contact face 15 having anangularly' disposed clo- 1 sure flange'ltw at oneside and an oppositeretaining flange, 171extending-iin the-same direction. Projecting fromthis retaining flange is an attaching flange 18 extended in adirectioncpposite to the flange17 and provided with'one or moreprojections 19 the flange lfi. This hook and slot are so slotted atintervals as shown at 26 and shown in Figure 14, the end strip, which isproportioned as to permit relative movement of the parts in order toproject the contact surface 15 against the sash. The casing 21 isformed'with a rebent portion from which the attaching strip 27 extendssubstantially parallel with the portion 22 and is secured by fasteningdevices, as at 28. The flange 22 has :1 turned free edge 22" to form areinforcement and tight joint.

Intermediate the side strip and easing a tenslon spring is disposedwhich may be of any preferred character, a. desirable form being offlatmetalasindicated at 29 havng corrugations 30 so as to provide a plu-*rality of'resilient faces extending for the length of the spring whichis substantiall commensurate with the length or strip use The unit sofar described comprises a side strip which -may be used independently ofother parts but for the purpose of providing a finished appearance andpreventing the entrance of dirt or moistureif exposed to theweather'thecasing isprovided with a closure plate 31 which is attachedat its inner end to the slotted portion 25 of the cas-- ing by means ofprojections 32 which are passed-'throughtheslots 26 and rehent as shownin Figure 3. The closure'plate 31 formed with the angle portion 33whichoverlaps the joint between the side strip and,

- its casing to protect the same and close the side openings therein.This portion has a turned edge 33 acting similarly to the edge 22'."This construction of side strip may be 'mounted'in' cooperation withthe end stripv 20 and the latter is. formed with the an gular attachingbody 34 secured within the channel 11 of the frame by any desired meanssuch as shownat 35, and'the' free end of this strip 20 is of resilientcharacter and has an extended bearing surface against the end of thesash as shown at 36 in Figure 3.

The free end of'this bearingsurface 36 is deflected at 37 to provide forits resilient hearing and the opposite-end of the portion,

36 is slotted at 38 to receivethe supporting lugs 19 from the sidestrip.The end of theangular portion '34: opposite the contact face 36"thereofisrebent as at 44 to form a stop to be engaged by the casing member 21and provide'an abutment.

Thismounting ofthe side strip permits 'mediatethe upper and lower sashto form the operating head as shown in Figure 13. If used in connectionWith a door 40 as similar to the construction before described, may bedisposed in an inclined channel 41 of the door frame 42 so that the sidestrip 'forms a stop or abutment for the door as at 43.

In assembling'the construction, the end strip may he firstmountediwit-hin the groove of thcwindow frame and the side strip havingits casing and enclosure memberpreviously connected therewith then slidinto engagement with the apertures of the end strip and secured by thefastening devices,

which assures a firm assemblage of the strips so that their tension maybe directly applied against thesash. The construction provides for aside unit which may be associated with a supplemental enclosing shelland mounted upon a cooperating end strip so as to secure pressureagainst both the side and end of a sash or door as shown in Figures 3and 14 respectively. This assemblage of parts practically supports thesash by the resilientmembers of the strips so as to prevent bindingorjannning thereof and affords a freely n'iovable window under allconditions. The closure cfl'ccied. prevents both the'entranccof air anddirt so as to effect economy in heating and also cleanliness of theapartment having the window to which the strip is applied. v p

.The parts vare adapted to be readily formed of sheet material bent intothe desired shape and can be applied by unskilled labor so as'to securethe most effective results in eatherstripping the window or door.

While the specific details of construction have been shown anddescribed. the invention is not confined thereto as changes andalterations may be made without departing fromthe spirit thereof asdefined by the following claims.
